Featuring magnetically coupled propeller drives and permanent-magnet brushless DC motors, Tecnadyne engineers have designed a new line of subsea thrusters that bring higher levels of propulsion efficiency to autonomous underwater vehicles. Dedicated to highly reliable systems for the subsea […]
Showcasing a sophisticated foray into electric propulsion and system electrification, Oceaneering unveiled its latest development in remotely operated vehicles for marine work projects at the Subsea Tieback Forum held in March at New Orleans. Named Momentum, the electric ROV was developed using a reliabilitydriven, datainformed design approach […]
Hydrogen offers promising potential application scenarios for ship propulsion. An electric motor installed in the drivetrain, which is supplied with energy from a fuel cell system, requires only a continuous supply of oxygen and hydrogen. Stored in […]
Azimuth thrusters, typically employing powerful neodymium permanent-magnet motors, have become a major tool for electrifying maritime propulsion. Kongsberg Maritime, a pioneering leader in the technology, has recently extended the range of its underwater mountable, permanent magnet azimuth […]
As the aviation industry works toward the ambitious goal of net-zero CO2 emissions by 2050, the shift to sustainable aviation fuel such as hydrogen is gaining momentum. However, truly effective reductions in the environmental impacts of aviation likely require innovation that goes beyond fuel to embrace the entire aircraft system. […]
Since the 1960s, academic, commercial and military researchers have attempted to realize a novel form of maritime propulsion involving no moving parts – no propeller, no drive shaft, no seals – just magnets and an electric current that silently propel a boat or submarine through water. It has been an elusive goal but tests are being conducted at Navy facilities this summer with an aim toward developing a practical, workable system. […]
Get an inside look at the engineering behind the innovative P-12 taxi hydrofoil straight from the team of Candela Technology in Stockholm who built it. To mark six months of successful operation in the Scandinavian […]
Swedish steel company Alleima will supply its Sanergy high-temperature pre-coated steel to Doosan Fuel Cell for its ramp-up to mass production of fuel cells for both maritime and stationary applications. The volume production is set to begin this year at a new manufacturing plant in Korea.
The Alleima material will be used for the interconnects, a key component in the fuel cell stacks. Alleima said in late January that it had received the order from Doosan which spans over two years for a total value of SEK 160 million. Deliveries were to start in the first quarter of 2025. […]
Leonardo DRS announced February 24 that it has received a $45 million U.S. Navy Submarine Industrial Base investment commitment through contracts with Huntington Ingalls Industries’ (HII) Newport News Shipbuilding. The investment is expected to expand the […]
With subsea projects ongoing in Japan, Scotland and France, Proteus Marine Renewables is spearheading the commercialization of marine renewable energy with its innovative tidal power products and services. The company’s core product uses permanent magnet generators […]
